Oahspe: A New Bible is a book published in 1882, purporting to contain "new revelations" from "...the Embassadors of the angel hosts of heaven prepared and revealed unto man in the name of Jehovih..." It was produced by an American dentist, John Ballou Newbrough (1828–1891), who reported it to have been written by automatic writing, making it one of a number of 19th-century spiritualist works attributed to that practice. The text defines adherents of the disciplines expounded in Oahspe as "Faithists".

Automatic writing, also called psychography, is a claimed psychic ability allowing a person to produce written words without consciously writing. Practitioners engage in automatic writing by holding a writing instrument and allowing alleged spirits to manipulate the practitioner's hand. The instrument may be a standard writing instrument, or it may be one specially designed for automatic writing, such as a planchette or a ouija board.
